Everything in an airline pilot's career is based on seniority. The definition of SENIORITY....status obtained as the result of a person's length of service. Seniority as you should know is everything! It dictates what equipment you fly, from what domicile and in what seat. Seniority determines when you fly, whether or not you're going to get weekends off, or if you are going to be home for Christmas, Thanksgiving, or your kids birthday. Let's see, didn't America West start up in the early 80's?
Besides this issue is over. DATE OF HIRE

If this was so binding why did ALPA testify in court at the MDA suit that the NIC was only a proposal? It's over...if you do not like it maybe you should consider going back to flight instructing....just a thought.
